What I'm looking for

I’m looking for a role where I can turn complex data into actionable insights through Python/SQL and Power BI, build reliable dashboards and predictive models, and keep improving via real-world datasets and strong feedback.

I’m an entry-level data analyst with hands-on experience in data analysis, data visualization, and dashboard development. I built a capstone on FARS 2022 crash data (39K+ records), combining EDA, feature engineering, and predictive modeling (Random Forest, XGBoost, LightGBM) to classify crash severity, achieving ROC-AUC 0.86 and strong F1 performance.

In industry, I worked as a Data Analyst Intern where I collected and processed data from Excel and SQL sources, improving analysis efficiency by 40% and delivering interactive Power BI dashboards that made reporting 20% faster. I also completed Data Science specialization work (GenAI), applying supervised/unsupervised ML and exploring NLP and Retrieval-Augmented Generation (RAG) to build data-driven solutions.
